CAR-VENTILATOR.

SPECIFATION fOrmiIlg part of Letters Patent NO. 538,298, dated April 30,1895.

Application filed January 17, 1895. Serial No. 535.256. (No model.) Y

To @ZZ whom t may concern.:

Be it known that I, J AMES TIMMs, of Columbus, in the county of Franklinand State of Ohio, have invented certain new and useful Improvements inOar-Ventilators; and I do hereby declare the'following to bea full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in car ventilators, it beingparticularly applicable to passenger and fruit cars, the object being tocreate a continuous circulation of tempered fresh air through the carand it consists in certain novel features of construction andcombinations of parts which will be hereinafter described and pointedout in the claims.

In the accompanying drawings Figure 1 is a view in side elevation of acar equipped with my improved heating and Ventilating apparatus.` Fig. 2is a plan view. Fig. 3 is an enlarged plan view of the Windowventilator. Fig. 4 is a side elevation of the same, and Fig. 5 is an endview.

A, represents acar, in this instance a passenger car although as abovestated my improved apparatus is equally applicable to other cars,especially fruit cars. At some convenient point beneath the car eitherat the center, or at the sides the air chamber l is located, the objectof which chamber is to receive aconstant supply of fresh air fromoutside the car and prepare it for regulating the temperature of thecar, that is to say, for heating the air in cold weather and cooling itin warm weather. For heating the air steam or hot water coils may beprovided or other means, not shown and for cooling the air chamber maybe filled or partially filled with ice. To this air chamber l, a pipe 2leads from each end of the car and the pipes 2, 2, are provided withhoods 3 at their upper ends as indicated, adapted to catch a continuoussupply of air as the car travels forward in either direction. Thesehoods have funnel shapedopenings at each end, whereby to receive air ineither direction of the cars motion and to control thefpassage of theair. A valve t is located at each end of the hood, one of which isalways open and the other always closed according to the direction oftravel of the car. These valves may be automatic in their operation' orthey may be controlled in any suitable manner.

One or more pipes, 5, 5, are passed through the floor of the car or atsome other convenient point in the car and these pipes are incommunication with the air chamber l from which they are supplied withair, the 'air escaping into the car through perforations 6, 6, withwhich the pipes 5, 5, are provided throughout their length. In thismanner a continuous supply of fresh air is taken in, discharged into theair chamber, then cooled or heated as the case may be and thencedischarged into the car for regulating the temperature of the latter.Valves (not shown) may of course be provided for controlling thisdischarge, to insure a proper degree of heat. Foul air is removed bysuction, through the .ventilatorwindows at the top of the car,

induced by the motion of the car in either direction. e

As many of these ventilators may be employed as are required to removethe air and as they are all alike one only will be described.

B, indicates this ventilator. It consists of an outer box or` caseadapted to fit the ventilating opening atthe top of the car. The heightof this ventilator corresponds to the height of the opening in which itis placed and in horizontal section it is restricted in width at thecenter 9 and enlarged or flaring at both ends l0, l0, to take the airfrom the inside and outside of the car, a valve ll, resembling the frogof a railway switch pivoted centrally at each end constituting adividing or partition wall between the two inlets at each'end and theother valve being always turned to deflect the siphoned air outward.Thusin Fig. 3 the outside air is scooped in at b and owing to theposition' of the valve at the other end, passes out at c and in passingthe point d creates suction therein, drawing air from the car, in at eso that a constant outpouring-of air is taking place from the carthrough the ventilators., In going the other way the valves ofcourse arereversed and the same action takes place and for convenience in turningthese valves, handles or similar means l2, l2 are provided. Thus it willbe seen that no dust, cinders or smoke can be drawn in through theventilators. It will be noticed IOO also that the ventilators arecompact, taking little space; they are neat and not unsightly; they aresimple and not likely to get out of order, and easily manipulated andcontrolled. lVith the arrangement of supplying and exhausting the air acomplete circulation is kept up and a continuons supply of fresh air istaken in to take the place of the eX- hansted -foul air.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described Without departing from thespirit and scope of my invention and hence I do not wish tolimit myselfto the exact construction herein set forth, but,

Having fully described my invention, what Ielaim as new, and desire tosecure by Letters Patent, is-

l. A ventilator consisting of a box or case open at the ends, having twovalves therein centrally pivoted at the outer ends of the zo case andextending toward each other whereby air passages are formed on each sideof the valves, substantially as set forth.

2. A ventilator comprising a case restricted at the center and open andflaring at the ends, and a valve centrally pivoted at each end, the freeends of said valves terminating in proximity to each other, one of saidvalves adapted to form a ldividing or partition Wall while the otherserves as a detleetor, substantially as set 3o forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing,r Witnesses.-

JAMES TIMMS.
